' BUTLER, OF 'WA'IERVILLE, MAINE.

SPIKE-FULLER.

Application filed August 17, 1917.

To all whom it may concern.

Be it known that I, HARRY BUTLER, a citizen of the United States, residing at Vaterville, in the county of Kennebec and State of Maine, have invented new and useful Improvements in Spike-Pullers, of which the following is a specification.

This invention relates to a Spike pullerand more particularly to a device for pulling spikes from railroad ties.

One of the objects of the invention is to provide a device which may readily be mounted upon a base portion or jack to be placed beside the track, said base providing a firm support at a proper elevation with reference to the tie, and said device including a plurality of pivoted jaws operated by a lever mounted on the base.

A further object is to provide a spike extracting member comprising a plurality of jaws having shank portions forming guiding members movable with reference to each other, said movement being controlled by a plurality of arms secured to the jaws and carried by a transverse member operated through the medium of a hand lever.

In the accompanying drawings:

Figure 1 is a view in side elevation with the jaws in open position.

Fig. 2 is a perspective view with the jaws in closed position.

In carrying out my invention I provide a base portion designated 10 having an upper portion 12 providing a fulcrum for a lever 14 comprising a handle portion 15 and an operating arm 16. The lever is fulcrumed at 17. A transverse member 18 comprises a plate or the like in which is mounted a bolt 20 connected with one end of arm 16 of the lever at point 21.

An arm 23 is connected with one end of plate 18 and extends downwardly therefrom, being deflected toward the opposite portion of said plate, and said opposite end of pl 18 supports a plurality of arms 25 and 26 extending downwardly and deflected in a direction opposite to the deflection shown by arm 23. These arms control the jaws of the spike extracting device, said jaws being designated 28 and 29 and having shank portions 30 and 31 extending therefrom respectively. The jaw and their shank portions may have substantially the curvature indicated in the drawing, and the extreme ends of portions 30 and 31 cooperate in such man- Specification of Letters Patent.

ner that one of these members forms a guide for the other which telescopes thereinto.

Each jaw is provided wlth an engaging end portion cut away to form a recess 33 or for contacting with the spike and espe cially the head thereof. The downwardly extending arms carried by transverse member 18 have connection with the jaws at points slightly distant from the engaging ends of the latter, and in operation pressure upon handle 15 will cause the elevation of the opposite end of the lever and the corresponding elevation of transverse member 18, the movement of the arms 23, 25 and 26, and the movement of the jaws toward each other for engaging the head of the spike. The relative position of the arms 23, 25 and 26, certain of these arms being deflected at an angle t others of said arms oppositely located, will of course produce a positive and effective grip on the head of the spike.

I claim 1. In a device of the class described, a plurality of jaws, a transverse member, an arm carried by one end of said m m er and extending downwardly therefrom and deflected toward the opposite end of the member and connected with one jaw, a plurality of arms connected with said opposite end and with the other of said jaws, a supporting member and a lever carried thereby and connected with said transverse member.

2. In a device of the class described, a plurality of jaws having shank portions, the shank portion of one jaw being provided with an opening receiving the shank portion of the other of said jaws, a transverse mem ber, devices connected with opposite ends of the transverse member, said devices being deflected in opposite direction and toward each other and having connection with the respective jaws, and means for operating said transverse member.

3. In a device of the class described, a plurality of jaws each having a shank portion, said jaw and its corresponding shank portion forming a member substantially U-shaped in configuration and the shank portion of one jaw being provided with an opening receiving the shank portion of the other jaw, and means for operating said jaw for gripping a spike or the like.

In a device of the class described, a plurality of jaws, each having a shank portion, each of said jaws and its corresponding each other, a transverse member, arms connected with the ends thereof and deflected toward each other near the ends of the jaws, said arms having connection with a given jaw oppositely located with reference to the mounting of said arm on the transverse member, a supporting device, and means mounted thereon for operating the transverse member and causing the operation of the jawsthrough the'mediumof said arms. In testimony whereof I affix my signature.

HARRY BUTLER.
